Betreff: Re: [Exim] authenticated_sender not attaching AUTH to MAIL
More info about this....

when I do a debug_print of authenticated_sender just after I've set it,
its empty. The expansion seems to be happening AFTER the debug_print, so
does debug_print always get done first and then the rest ?
If I hardwire authenticated_sender rather than relying on expansion, its
still empty according to debug_print....

so I can only assume that something's wrong with the way I've got exim
talking to lmtp.

The docs for smtp transport say this about authenticated_sender:
" When Exim has authenticated as a client, this option sets a value for
the AUTH= item on outgoing MAIL commands, overriding any existing
authenticated sender value. If the string expansion is forced to fail,
the option is ignored. Other expansion failures cause delivery to be
deferred. If the result of expansion is an empty string, that is also
ignored.
"
I'm wondering if that first statement is nullifying the whole thing.
"when exim has authenticated as a client..." is past tense, so does
using pre-auth on lmtpd somehow screw the whole thing up ? (maybe exim
thinks that its not really auth'ed ?)



cheers
